Nitrogen-fixing bacteria (bacteria that convert atmospheric nitrogen to absorbable form) are found growing in the roots of certain plants called leguminous plants (E.g: pulses). If these plants are grown after a harvest, they will help restore the nutrients which were used up from the soil during the harvest. Rajma, peas, moong and gram are examples of leguminous plants.
